    1. INTRODUCTION Congratulations on your choice of the SUUNTO VYPER advanced dive computer. This dive computer is a compact and sophisticated multipurpose dive instrument that will give you years of trouble-free and joyful diving. 1.1. SAFETY PRECAUTIONS Do not attempt to use the dive computer without reading this instruction manual in its entirety, including all the warnings below.
  • Page 9 NO PROCEDURE, DIVE COMPUTER OR DIVE TABLE WILL PRE- VENT THE POSSIBILITY OF DECOMPRESSION SICKNESS (DCS) OR OXYGEN TOXICITY! You must understand and accept that there is no pro- cedure, dive computer or dive table that will totally prevent the possibility of a decompression accident or that oxygen toxicity will not occur, even within accepted limits.

  • Page 10: Emergency Ascents

    ENSURE THE WATER RESISTANCE OF THE DEVICE! Always check the water resistance of the battery compartment when replacing the battery. Moisture inside the device or battery compartment will seriously damage the unit. Only an authorized SUUNTO dealer or distributor should do service activities. 1.1.1. Emergency Ascents In the unlikely event that the dive computer malfunctions during a dive, follow the emergency procedures provided by your certifi...

  • Page 11: Dive Computer Limitations

    1.1.2. Dive Computer Limitations While the dive computer is based on current decompression research and technol- ogy, you must realize that the computer cannot monitor the actual physiological functions of an individual diver. All decompression schedules currently known to the authors, including the U.S. Navy Tables, are based on a theoretical math- ematical models, which are intended to serve as a guide to reduce the probability of decompression sickness.

  • Page 18: Dive Planning [Plan]

    3.1.3. Dive Planning [PLAN] It is possible at any time in the Surface Mode to enter the Planning Mode, simply by pressing the PLAN button. After showing the text PLAN (Fig. 3.6), the display will show the no-decompression limit for the depth of 9 m [30 ft]. By pressing the arrow down TIME (t) button, the dive computer will calculate and show the next deeper no-decompression limits in 3 m [10 ft] increments ending at 45 m [150 ft].

    200 minutes, the fi rst (lowest) bar graph segment appears. As your body absorbs more nitrogen, more segments start to appear. Green Zone - As a safety precaution SUUNTO recommends that when using this dive computer you should maintain the no-decompression bar graph within the green zone.

  • Page 22: Safety Stop Displays

    3 m - 6 m [10 ft - 20 ft]. RECOMMENDED SAFETY STOP SUUNTO highly recommends a safety stop at the end of every dive in the range of 3 m - 6 m [10 ft - 20 ft] for at least 3 minutes. This is shown with...

  • Page 23: Ascent Rate Indicator

    The Mandatory Safety Stop time always includes the three-minute Recom- mended Safety Stop time. The total length of the Mandatory Safety Stop time depends on the seriousness of the ascent rate violation. You must not ascend shallower than 3 m [10 ft] with the Mandatory Safety Stop warning on.
  • Page 24 STOP NO DEC TIME ° DIVE TIME Fig. 3.13 Ascent Rate Indicator. Blinking depth reading, SLOW and four segments shown: ascent rate is more than 10 m/min [33 ft/min]. This is a caution to slow down! The STOP sign means that you are advised to make a Manda- tory Safety Stop when you reach the depth of 6 m [20 ft].

  • Page 25: Decompression Dives

    3.2.5. Decompression dives When your NO DEC TIME becomes zero, your dive becomes a decompression dive, i.e. you must perform one or several decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME notation and the maximum depth will be replaced by a CEILING notation and an upward pointing arrow (Fig.
  • Page 26 YOU SHOULD ASCEND AND BEGIN DECOMPRESSION IMMEDIATELY WHEN THE DIVE COMPUTER SHOWS YOU THAT DECOMPRESSION IS REQUIRED! Note the blinking ASC TIME symbol and the upward pointing arrow. YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DISPLAYED BY THE INSTRUMENT. The ascent time will increase if you: - remain at depth - ascend slower than 10 m/min [33 ft/min] or - make your decompression stop deeper than at the ceiling.
  • Page 27 SUUNTO recommends that decompression takes place deeper than 4 m [13 ft], even if the indicated ceiling is shallower.

  • Page 36: Flying After Diving

    - Following any dive that required a decompression stop, fl ying should be delayed for at least 24 hours, and if possible, for 48 hours. SUUNTO recommends that fl ying is avoided until all the DAN and UHMS guidelines and the dive computer wait to fl y conditions are satisfi ed.

  • Page 37: Audible And Visual Alarms

    3.6. AUDIBLE AND VISUAL ALARMS The dive computer features audible and visual alarms to advise when important limits are ap- proached or to acknowledge preset alarms. A short single beep occurs, when: • the dive computer is activated • when the dive computer automatically returns to the TIME Mode.
  • Page 38 You are able to set alarms before the actual dive. The preset user programmable alarms can be set for time, dive time and maximum depth. The alarms activate when: • The preset alarm time is reached (Fig. 3.31) - the current time is shown - continuous beep series for 24 seconds or until any button is pressed - the current time blinks for one minute, if no button is pressed.

When diving at altitudes greater than 300 m [1000 ft] the Altitude Adjustment feature must be correctly selected in order for the computer to calculate no-decompression status.
  • Page 41 The Personal Adjustment Mode is indicated by a diver symbol and plus signs (P0 = a diver, P1 = diver +, or P2 = diver ++). Section 4.3.1.1. “Altitude Adjustment and Personal Adjustment Setting” describes how the Personal Mode is adjusted. This feature should be used to adjust the computer to be more conservative, according to personal preference, by entering the suitable Personal Adjustment Mode with the help of Table 3.4.

    ALTITUDE DIVING The atmospheric pressure is lower at high altitudes than at sea level. After traveling to a higher altitude, the diver will have additional nitrogen in his body, compared to the equilibrium situation at the original altitude. This “additional” nitrogen is released gradually in time and equilibrium is reached within a couple of days.
